SEARCH-LIGHT.

To all whom 'it may concern:

Be it known that I, MYRON L. Snvmzson, a citizen of the United States,residing at Passaic, in the county of Passaic and State of New Jersey,have invented new and useful Improvements in Search-Lights, of which thefollowing is a specification.

This invention is designed primarily to provide a search light which maybe operated from a distant point and yet admit of the beam of lightbeing thrown to any elevationor to any angle so as to illuminate anydesired point.

The invention provides a mechanism utilizing fluid as the powertransmitting means in the adjustment of the light both with reference toaltitude and horizontal angular ad ustment.

'lhe invention provides a search light which may be mounted upon themast of a or'located in any convenient position an adapted to beoperated from a distant oint without exposing the manipulator, theinvention bein of special advanta e in locatin the lig t upon the mastoi a ship or ot er elevated point.

The invention consists of the novel features, details of constructionand combination of arts, which hereir fter will be more particu arly setforth, illustrated in the accompanyin drawings, and pointed out in the apen ed claims.

Re erring to the drawings, forming a partof the specification, Figure 1is a view in elevation of a search light and operating means embodyingthe invention. Fig. 2 is a vertical section of the lamp su port and thecontrolling means admitting o directing the beam of light in the desireddirection. Fig. 3 is a horizontal section on the line H of Fig. 2. Fig.4 is a horizontal section on the line 3 of Fig. 2, lookin upward, asindicated hy the arrows. lg. 5

is an enlarged section of the'cylinder and means whereby the lamp isturned about a vertical axisl Corresponding and'like parts are referredto in the following descrl tion, and indicated in all the views oft edrawings, by the same reference characters.

(The lamp support 1 consists of a stand of suitable construction, thesame having a vertical 0 ening 2 and bores 3 and 4 forming cylin ers inwhich pistons 5 and 6. are arranged to operate. The lamp 7 forpropecificatlon of Letters Patent.

jecting the search light may he of any construction and is mounted uponan upri ht 8 so as to'turnabout a vertical and a lint-i zontal axis toadmit of throwing the beam of light in the required direction bothhorizontally and vertically. A sleeve 9 is mounted in the opening 2 andhas a flange 10 at its upper end to extend over the stand 1 and supportthe sleeve within the opening 2. The upright 8 is mounted upon theflange 10 of the sleeve 9. The pivotalconnection 11 of the upright 8with the lamp 7 is to one side of the vertical axis about which the lampturns. The upper end of the part 8 is forked, the fork members beingpivotally connected to opposite sides of the lamp 7. A pinion 12 issecured to the lower end of the sleeve 9 and meshes with a toothedsegment 13 secured to the lower end of a stem 14 which extends into thecylinder 4. When the lamp is arranged to oint straight ahead or inlinewith the travel of a vessel the middle portion of the segment 13 is inmesh with the pinion 12 so that upon turning the stem 14 either to theright or to-the left the lamp is caused to make a correspondingrevolution. Suitable stops 15 are had to limit the movements of thetoothed segment 13 in each direction. The piston 6 is revented fromturning in the cylinder 4, t is being accomplished .by means of a stud16 on the piston entering a vertical groove 17 formed in the wall of thecylinder 4. The piston 6 has a hollow stem 18 which receives the stem14. -A spiral slot formed in the hollow stem 18 re- 'ceives a stud 20projecting from the stem 14, hence movement of the piston 6 in thecylinder 4 causes rotation of the stem 14 and a like movement of thetoot-lied segment 13 and the latter meshing with the pinion 12 turns thesleeve 9 and the lamp 7 so as to project the beam of light in thedesired direction. .A passage 21 is formed in the stand 1 andcommunicates with the upper end of the cylinder 4. A pipe 22 connectswith the passage 21 and with a suitable source of supply of compressedair or ot-her fluid motive medium. A two-way cock 23 is located in thelength of the pipe 22 at a convenient point and by manipulatin saidvalve a fluid medium may be admitte into .the cylinder 4 or exhaustedtherefrom. When the two-way cock 23 is turned to out inder 4 and to openthe outlet the piston 6 is moved upwardly in the cylinder by means of anexpansible helical spring 24.

A rod 25 is mounted in the sleeve 9 and extends therethrough. A link 26connects the upper end of the rod 25 with the lam 7. Ball and socketjoint connections are liad between the link 26 and the lamp and the rod25 to admit of angular adjustment of the lamp as well as verticaladjustment thereof. The lower portionof the rod 25 extends laterally, asindicated at 27, thence vertically, as shown at '28, and connects withthe piston 5. A spring 29 of the expansible helical type is located inthe cylinder 3 and normally exerts an upward pressure upon. the piston5. A passage 30 is formed in the stand 1 and communicates at its upperend with the cylinder 3. A pipe 31 connects with the passage 30 andleads to a suitable source of supply of compressed air or other fluidmedium. A two-way cock 32 is located in the length of the pipe 31. Uponturning the cock 3?. to supply compressed air or other fluid medium tothe upper end of the cylinder 3 the piston 5 is depressed, therebymoving the rod 25 downwardly and throwing the beam of light upwardly.Upon moving the cock 32 to a position to relieve the upper end of thecylinder 3 of pressure the spring 29 forces the piston 5 upwardly,thereby elevating the rear end of the lamp an throwing the beam of ii htdownwar ly. By proper adjustment 0 the controlling means 23 and 32 thelamp 7 may be moved so as to throw the beams of light to any altitudeand horizontal angular adjustment as may be required.

From the fore oing description, taken in connection with t eaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchan s may be made when desired as are within the scope of the claimsappended hereto.
